Your car’s radiator plays an important role in the operation of the vehicle as combustion engines require this component to prevent overheating. The radiator is connected to a number of channels which run throughout your vehicle’s engine and cylinder head. Liquid coolant, (usually a mixture of water and ethylene glycol), is pumped through these components to transport heat away from them and allow the heat to be radiated into the air, away from the working parts. The liquid flows through a thermostat and returns again, back to the radiator. In this way, the heat is conducted out of the engine parts, preventing your car or truck from overheating.

To keep your radiator, the fluid it contains, and the engine in good condition, the radiator is mounted behind the grille of the vehicle so that cold air will be driven through it during operation. There is a complex system of valves which simultaneously operate a smaller internal version of a radiator called the heater core. This delivers hot air to the cabin when the driver wants to warm up the interior of the vehicle.

The thermostat is another critical component of your car’s cooling system. It remains closed and will restrict the flow of coolant until the engine reaches the activation temperature. When properly calibrated, this allows the engine to stay within its ideal temperature range. The thermostat closes to allow heat to build in the engine. When the engine temperatures get too low it opens and allows heat to be removed when the engine temperatures become too high.

The radiator was invented by Karl Benz. Today, some engines have additional oil coolers to cool the motor oil while the majority of turbo-charged engines feature an intercooler.

Today, the most advanced version of this technology is the universal aluminum radiator. Aluminum conducts and releases heat much more effectively than traditional coolers, which are made from brass, can do. Due to modern machining science, aluminum is much easier to use in the manufacturing process. These advances have lead to the advent of the universal aluminum radiator. This modern version of the radiator offers superior performance and are compatible with a much wider range of vehicles.
